Comparative Study of Myringoplasty Outcome with and without Cortical Mastoidectomy

Open Access

Abstract

Introduction: Chronic suppurative otitis media (CSOM) is an infection of the middle ear that is very common. It is mainly characterized by persistent perforation of the tympanic membrane, recurrent discharges from the ear, and hearing loss due to conduction. The study is designed to evaluate and analyze the results of myringoplasty along with cortical mastoidectomy versus those of myringoplasty alone. Methods & Matetials: This comparative study was conducted on 100 patients with tubotympanic chronic suppurative otitis media attending the ENT department at Specialized ENT Hospital of SAHIC, Dhaka  from January 2025 to December 2025. Patients were randomly divided into two equal groups: Group A, which had 50 patients who underwent myringoplasty alone, and Group B, which had 50 patients who underwent myringoplasty with cortical mastoidectomy. Data were analyzed using SPSS version 25.0. Result: Both groups in the study of 100 patients were similar in terms of age and gender distribution. The two groups also had similar perforation size and site. There was no significant difference between the two groups in terms of graft uptake, which was high in both groups (86% for myringoplasty only vs. 90% with mastoidectomy). Hearing was improved in both groups, with a significantly greater air-bone gap closure found in the group that underwent mastoidectomy. (14.9 ± 4.6 dB vs. 11.8 ± 4.1 dB, p = 0.01). Postoperatively, most patients achieved a dry ear (82% vs. 88%), and minor complications were rare and comparable. Conclusion: Both myringoplasty, with or without cortical mastoidectomy, show high rates of graft uptake and satisfactory postoperative ear status in tubotympanic chronic suppurative otitis media. Although cortical mastoidectomy did not significantly enhance graft success or ear dryness, it was related to more hearing improvement.
